- In recent decades, nanoparticles-based research has attracted more towards the degradation of toxic pollutants from various industries and in nanomedicine development. In this study, we have investigated on CuO@SiO2nanoparticles catalytic degradation of 4-nitrophenol as a model and their antimicrobial activity studies. The previously characterized CuO nanoparticles were doped onto SiO2 nanoparticles, synthesized from rice husk and was characterized by XRD. The doped nanoparticles were characterized by FTIR spectrum. The reduction of 4-nitrophenol to 4-aminophenol by NaBH4 with synthesized and doped nanoparticles as a catalyst were systematically studied to exhibit the catalytic performance of the nanoparticles. It has been observed that the catalytic efficiency of CuO@SiO2 is higher than the CuO and SiO2 nanopartcles. The doped nanoparticles antimicrobial activity was evaluated and observed that doped nanoparticles have significant antimicrobial activity. Hence, this study makes a platform for CuO@SiO2 nanomaterials usage for the degradation of toxic pollutants and antimicrobial agent against pathogenic microorganisms.
